Description

本発明は、バッテリ保護構造に関し、特に、バッテリの車両外側に配置されたダクトにより衝突事故発生時の衝撃を吸収するバッテリ保護構造に関する。 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a battery protection structure, and more particularly to a battery protection structure in which a duct arranged outside the vehicle of the battery absorbs an impact when a collision accident occurs.

乗用車等の車両として、ハイブリッド自動車や電気自動車が登場してきており、これらの車両には大型の充電式バッテリが搭載されている。車両に搭載される充電式バッテリは、例えば略板状に形成されたバッテリセルと呼称される単体のリチウムイオンバッテリを複数個組み合わせたモジュールから構成される。 Hybrid vehicles and electric vehicles have appeared as vehicles such as passenger cars, and these vehicles are equipped with large rechargeable batteries. 2. Description of the Related Art A rechargeable battery mounted on a vehicle is composed of a module in which a plurality of single lithium-ion batteries, which are called battery cells formed in a substantially plate shape, are combined, for example.

車両に衝突事故が発生した場合、充電式バッテリに大きな衝撃が作用すると漏電やガス発生の恐れがあるため、充電式バッテリに及ぶ衝撃を緩和するための衝撃対策が必要とされる。 In the event of a vehicle collision, if the rechargeable battery is subjected to a large impact, there is a risk of electrical leakage or gas generation.

このような衝撃対策の一例として、以下の特許文献1に記載された発明が存在する。 As an example of such shock countermeasures, there is an invention described in Patent Document 1 below.

特許文献1では、衝撃吸収ダクトでバッテリを保護するバッテリ搭載部のエネルギ吸収構造が記載されている。具体的には、このエネルギ吸収構造では、バッテリ搭載部は、衝撃吸収ダクトにより車体フロアとセンターコンソールボックスとを連結している。また、バッテリ搭載部は、センターコンソールボックスから、所定値以上の荷重が入力すると、変形することでエネルギ吸収を行う。よって、側面衝突時にセンターコンソールボックスから衝撃吸収ダクトへ所定値以上の荷重が入力されると、衝撃吸収ダクトが曲げ変形することによって、バッテリに入力する衝撃エネルギが低減される。 Patent Literature 1 describes an energy absorption structure for a battery mounting portion that protects the battery with an impact absorption duct. Specifically, in this energy absorbing structure, the battery mounting portion connects the vehicle body floor and the center console box with an impact absorbing duct. Further, when a load of a predetermined value or more is input from the center console box, the battery mounting portion deforms to absorb energy. Therefore, when a load of a predetermined value or more is input from the center console box to the shock absorbing duct in the event of a side collision, the shock absorbing duct bends and deforms, thereby reducing the impact energy input to the battery.

以下、本発明の実施形態に係るバッテリ保護構造10を図面に基づき詳細に説明する。 A battery protection structure 10 according to an embodiment of the present invention will be described in detail below with reference to the drawings.

図1は、バッテリ保護構造10が組み込まれた乗用車等の車両を部分的に示す斜視図である。ここでは、車体フロア18の前方外側部分を示している。 FIG. 1 is a perspective view partially showing a vehicle such as a passenger car in which a battery protection structure 10 is incorporated. Here, the front outer portion of the vehicle body floor 18 is shown.

本実施形態に係るバッテリ保護構造10は、自車に対して他車が車両外側から衝突する側突により入力する衝撃エネルギを吸収し、バッテリ11を当該側突から保護する構造である。具体的には、バッテリ保護構造10は、車両骨格部材であるクロスメンバ121およびクロスメンバ122と、クロスメンバ121に形成した第1貫通孔131と、空調ダクト152と、バッテリダクト14と、を具備しており、バッテリ11よりも車両外側で、空調ダクト152とバッテリダクト14とが重畳している。ここで、バッテリダクト14が第1ダクトであり、空調ダクト152が第2ダクトである。また、前方に配置されたクロスメンバ121が第1車両骨格部材であり、クロスメンバ122が第2車両骨格部材である。 The battery protection structure 10 according to the present embodiment is a structure that absorbs impact energy input when another vehicle collides with the own vehicle from the outside of the vehicle and protects the battery 11 from the side impact. Specifically, the battery protection structure 10 includes a cross member 121 and a cross member 122 that are vehicle frame members, a first through hole 131 formed in the cross member 121, an air conditioning duct 152, and a battery duct 14. The air-conditioning duct 152 and the battery duct 14 overlap each other outside the battery 11 . Here, the battery duct 14 is the first duct, and the air conditioning duct 152 is the second duct. Further, the cross member 121 arranged forward is the first vehicle frame member, and the cross member 122 is the second vehicle frame member.

バッテリ11は、電動車である車両のモータや電装部品に、電力を供給する。ここで、車両としては、例えば、EV(Electric Vehicle)、HEV(Hybrid Electric Vehicle)やPHEV(Plug-in Hybrid Electric Vehicle)等を採用できる。 The battery 11 supplies electric power to the motor and electrical components of the vehicle, which is an electric vehicle. Here, as the vehicle, for example, an EV (Electric Vehicle), an HEV (Hybrid Electric Vehicle), a PHEV (Plug-in Hybrid Electric Vehicle), or the like can be adopted.

バッテリ11は、ここでは図示しないが、積層配置された多数のバッテリセルから成るバッテリスタックを複数個有している。また、バッテリ11は、リチウムイオンバッテリまたはニッケル水素バッテリから成る二次電池である。 Although not shown here, the battery 11 has a plurality of battery stacks composed of a large number of battery cells arranged in layers. Also, the battery 11 is a secondary battery composed of a lithium ion battery or a nickel metal hydride battery.

車体フロア18には、車両骨格部材として、フロアトンネル16およびサイドシル17が形成されている。フロアトンネル16は、車体フロア18の車両幅方向における中心部分を、前後方向に沿って上方に隆起させた骨格部材である。サイドシル17は、車体フロア18の車両外側端部を前後方向に沿って柱状に成形した骨格部材である。バッテリ11は、フロアトンネル16と、サイドシル17との間に配置されている。 A floor tunnel 16 and side sills 17 are formed on the vehicle body floor 18 as vehicle frame members. The floor tunnel 16 is a skeletal member in which the central portion of the vehicle body floor 18 in the vehicle width direction is raised upward along the front-rear direction. The side sill 17 is a frame member formed by molding the outer end of the vehicle body floor 18 into a columnar shape along the front-rear direction. Battery 11 is arranged between floor tunnel 16 and side sill 17 .

更に、車体フロア18には、骨格部材としてクロスメンバ121およびクロスメンバ122が配置されている。クロスメンバ121はバッテリ11の前方側に配置される。クロスメンバ121の車両外側端部はサイドシル17に剛結され、クロスメンバ121の車両内側端部はフロアトンネル16に剛結される。クロスメンバ122はバッテリ11の後方側に配置される。クロスメンバ122の車両外側端部はサイドシル17に剛結され、クロスメンバ122の車両内側端部はフロアトンネル16に剛結される。 Furthermore, a cross member 121 and a cross member 122 are arranged as frame members on the vehicle body floor 18 . Cross member 121 is arranged on the front side of battery 11 . The vehicle-outside end of the cross member 121 is rigidly connected to the side sill 17 , and the vehicle-interior end of the cross member 121 is rigidly connected to the floor tunnel 16 . Cross member 122 is arranged on the rear side of battery 11 . The vehicle outer end of the cross member 122 is rigidly connected to the side sill 17 , and the vehicle inner end of the cross member 122 is rigidly connected to the floor tunnel 16 .

クロスメンバ121には第1貫通孔131が形成されている。第1貫通孔131はクロスメンバ121を前後方向に沿って貫通する孔である。第1貫通孔131は、バッテリ11の車両外側端部よりも車両外側に形成されている。第1貫通孔131は、後述する空調ダクト152を挿通させることが出来る大きさおよび形状とされている。 A first through hole 131 is formed in the cross member 121 . The first through hole 131 is a hole passing through the cross member 121 along the front-rear direction. The first through hole 131 is formed on the vehicle outside of the vehicle outside end of the battery 11 . The first through-hole 131 has a size and a shape that allow an air conditioning duct 152 (described later) to pass therethrough.

また、ここでは図示しないが、クロスメンバ121の上面にはシートが固定される。係る構成により、シートを支持する部材としてクロスメンバ121を用い、クロスメンバ121が空調ダクト152の引き回しを阻害することなく、更には、クロスメンバ121に形成した第1貫通孔131で空調ダクト152の耐衝撃性を向上できる。 Also, although not shown here, a sheet is fixed to the upper surface of the cross member 121 . With this configuration, the cross member 121 is used as a member for supporting the seat, and the cross member 121 does not hinder the routing of the air conditioning duct 152. Further, the first through hole 131 formed in the cross member 121 allows the air conditioning duct 152 to pass through. Impact resistance can be improved.

バッテリ11の車両外側にはバッテリダクト14が形成されている。バッテリダクト14は、バッテリ11が充放電する際に発する熱を外部に排出するためのダクトである。バッテリダクト14は、例えばPP(Polypropylene)から成る。 A battery duct 14 is formed outside the vehicle of the battery 11 . The battery duct 14 is a duct for discharging heat generated when the battery 11 is charged and discharged to the outside. The battery duct 14 is made of PP (Polypropylene), for example.

空調ダクト15は、車室を空調するための空調風が流通するダクトである。具体的には、空調ダクト15は、空調風の上流側に形成された空調ダクト151と、空調ダクト151の下流側端部から枝分かれする空調ダクト153および空調ダクト152と、を有する。空調ダクト15は、例えば、例えばPP(Polypropylene)から成る。 The air-conditioning duct 15 is a duct through which air-conditioning air for air-conditioning the vehicle compartment flows. Specifically, the air-conditioning duct 15 has an air-conditioning duct 151 formed on the upstream side of the air-conditioning air, and an air-conditioning duct 153 and an air-conditioning duct 152 branching from the downstream end of the air-conditioning duct 151 . The air conditioning duct 15 is made of, for example, PP (Polypropylene).

空調ダクト151の上流側端部は、車両空調装置に接続され、空調ダクト151の下流側端部には空調ダクト152および空調ダクト153が接続している。 The upstream end of air conditioning duct 151 is connected to the vehicle air conditioner, and the downstream end of air conditioning duct 151 is connected to air conditioning ducts 152 and 153 .

空調ダクト152の上流側端部は空調ダクト151に接続し、空調ダクト152の下流側端部は、ここでは図示しない車室に開口している。また、空調ダクト152の中間部分は、クロスメンバ121の第1貫通孔131を貫通し、クロスメンバ122の上方を通過する。また、クロスメンバ121とクロスメンバ122との間に於いて、クロスメンバ121は、バッテリ11よりも車両外側に配置されている。 The upstream end of the air-conditioning duct 152 is connected to the air-conditioning duct 151, and the downstream end of the air-conditioning duct 152 opens into the passenger compartment (not shown). An intermediate portion of the air conditioning duct 152 passes through the first through hole 131 of the cross member 121 and passes above the cross member 122 . Between the cross member 121 and the cross member 122 , the cross member 121 is arranged outside the vehicle from the battery 11 .

空調ダクト153の上流側端部は空調ダクト151に接続し、空調ダクト153の下流側端部は、ここでは図示しない車室に開口している。また、空調ダクト153の中間部分は、クロスメンバ121およびバッテリ11の上方を通過している。 The upstream end of the air-conditioning duct 153 is connected to the air-conditioning duct 151, and the downstream end of the air-conditioning duct 153 opens into a vehicle compartment (not shown). An intermediate portion of air conditioning duct 153 passes over cross member 121 and battery 11 .

本実施形態では、バッテリ11の車両外側に於いて、バッテリダクト14と空調ダクト152とを重畳させている。このようにすることで、側突が発生した際に、バッテリ11に作用する衝撃を緩和することができる。 In this embodiment, the battery duct 14 and the air conditioning duct 152 overlap each other on the vehicle outer side of the battery 11 . By doing so, it is possible to mitigate the impact acting on the battery 11 when a side collision occurs.

具体的には、バッテリ11の前方および後方にはクロスメンバ121およびクロスメンバ122が配置されている。一方、バッテリ11の車両外側にはサイドシル17が形成されているが、この部分にポール衝突が発生した場合、サイドシル17が局所的に内側に向かって湾曲し、バッテリ11に大きな衝撃が作用してしまう恐れがある。 Specifically, a cross member 121 and a cross member 122 are arranged in front of and behind battery 11 . On the other hand, a side sill 17 is formed on the vehicle outer side of the battery 11, and when a pole collision occurs in this portion, the side sill 17 is locally curved inward, and a large impact acts on the battery 11. There is a risk that it will be lost.

そこで、本実施形態では、バッテリ11の車両外側にバッテリダクト14および空調ダクト152を、上方から見たら重畳するように配置している。空調ダクト152およびバッテリダクト14は、上記したように合成樹脂から成るダクトであるため、ある程度の機械的強度を有している。よって、側突が発生した際に、空調ダクト152およびバッテリダクト14が同時に変形することで衝撃を吸収し、バッテリ11に作用する衝撃を緩和することができる。また、バッテリダクト14および空調ダクト152は、空調風を送風するための構成部材であり、衝撃対策のための専用部材ではないため、コスト上昇を抑制することができる。 Therefore, in the present embodiment, the battery duct 14 and the air conditioning duct 152 are arranged outside the vehicle of the battery 11 so as to overlap when viewed from above. Since the air conditioning duct 152 and the battery duct 14 are ducts made of synthetic resin as described above, they have a certain degree of mechanical strength. Therefore, when a side collision occurs, the air-conditioning duct 152 and the battery duct 14 are deformed at the same time to absorb the impact, and the impact acting on the battery 11 can be mitigated. Moreover, since the battery duct 14 and the air-conditioning duct 152 are components for blowing air-conditioning air, and are not exclusive members for shock countermeasures, cost increases can be suppressed.

図2は、図1の切断面線A-Aに於ける断面図である。図2では、バッテリ11の上端および下端と同レベルの高さを一点鎖線で示している。 FIG. 2 is a cross-sectional view taken along line AA in FIG. In FIG. 2, the height at the same level as the upper and lower ends of the battery 11 is indicated by a dashed line.

この図を参照して、バッテリ11は、フロアトンネル16とサイドシル17との間に於いて、車体フロア18の上面に配置されている。また、バッテリ11の車両外側には、バッテリダクト14および空調ダクト152が配置されている。上記したように、バッテリダクト14と空調ダクト152とは、上方から見て重畳するように配置されている。バッテリダクト14と空調ダクト152とは、両者が部分的に重畳しても良いし、空調ダクト152の全てがバッテリダクト14の上方に配置されても良い。 Referring to this figure, battery 11 is arranged on the upper surface of vehicle body floor 18 between floor tunnel 16 and side sill 17 . A battery duct 14 and an air conditioning duct 152 are arranged outside the vehicle of the battery 11 . As described above, the battery duct 14 and the air conditioning duct 152 are arranged so as to overlap when viewed from above. The battery duct 14 and the air conditioning duct 152 may partially overlap each other, or the entire air conditioning duct 152 may be arranged above the battery duct 14 .

更に、バッテリダクト14および空調ダクト152は、バッテリ11とサイドシル17との間に於いて、バッテリ11の側に寄せて配置されている。このようにすることで、側突が発生した際に、バッテリ11の近傍で、空調ダクト152およびバッテリダクト14が変形することで、側突による衝撃を効果的に吸収することができる。 Furthermore, the battery duct 14 and the air conditioning duct 152 are arranged between the battery 11 and the side sill 17 and closer to the battery 11 side. By doing so, when a side collision occurs, the air conditioning duct 152 and the battery duct 14 are deformed in the vicinity of the battery 11, so that the impact caused by the side collision can be effectively absorbed.

また、バッテリダクト14の下端は、バッテリ11の底面よりも上方に配置されている。更に、バッテリダクト14の上端は、バッテリ11の上面よりも下方に配置されている。係る構成により、側突が発生した際に、サイドシル17に押圧されたバッテリダクト14が効果的に変形することで、側突による衝撃を緩和し、バッテリ11を衝撃から保護することができる。 Also, the lower end of the battery duct 14 is arranged above the bottom surface of the battery 11 . Furthermore, the upper end of the battery duct 14 is arranged below the upper surface of the battery 11 . With such a configuration, when a side collision occurs, the battery duct 14 pressed by the side sill 17 is effectively deformed, thereby mitigating the impact of the side collision and protecting the battery 11 from the impact.

更にまた、空調ダクト152の少なくとも一部は、バッテリ11の上面よりも下方に配置されている。このようにすることで、側突が発生した際に、サイドシル17に押圧された空調ダクト152か効果的に変形することで、側突による衝撃を効果的に緩和し、バッテリ11を衝撃から保護することができる。ここで、空調ダクト152の全てを、バッテリ11の上面よりも下方に配置することも出来る。 Furthermore, at least part of the air conditioning duct 152 is arranged below the upper surface of the battery 11 . By doing so, when a side collision occurs, the air conditioning duct 152 pressed by the side sill 17 is effectively deformed, thereby effectively mitigating the impact caused by the side collision and protecting the battery 11 from the impact. can do. Here, all of the air conditioning ducts 152 can also be arranged below the upper surface of the battery 11 .

図3に、側突が発生した後のバッテリ保護構造10の構成を説明する。ここでは、図1の切断面線A-Aに示した箇所に、車両外側からポールが衝突するポール衝突が発生した場合を示している。先ず、ポール衝突が発生することで、サイドシル17は車両内側に向かって進入する。更に、サイドシル17に車両外側から押された空調ダクト152およびバッテリダクト14は、車両幅方向において圧縮されるように変形する。 FIG. 3 illustrates the configuration of the battery protection structure 10 after a side collision occurs. Here, there is shown a case where a pole collides with a pole from the outside of the vehicle at the location indicated by the section line AA in FIG. 1 . First, when a pole collision occurs, the side sill 17 moves toward the inside of the vehicle. Furthermore, the air conditioning duct 152 and the battery duct 14 pushed from the outside of the vehicle by the side sill 17 are deformed so as to be compressed in the vehicle width direction.

空調ダクト152の前方部分は、図1に示したように、クロスメンバ121の第1貫通孔131を貫通していることから、空調ダクト152の車両内側への移動は抑止されている。よって、側突時に空調ダクト152がサイドシル17により車両内側に押されたら、空調ダクト152はその位置を維持しつつ潰れ変形することで、衝撃を吸収する。 As shown in FIG. 1, the front portion of the air-conditioning duct 152 passes through the first through hole 131 of the cross member 121, so movement of the air-conditioning duct 152 toward the inside of the vehicle is suppressed. Therefore, when the air-conditioning duct 152 is pushed toward the inside of the vehicle by the side sill 17 in the event of a side collision, the air-conditioning duct 152 is crushed and deformed while maintaining its position, thereby absorbing the impact.

また、バッテリダクト14の車両内側端側の端部は、バッテリ11に接触している。よって、側突時には、バッテリダクト14は、サイドシル17により車両外側から押されることで、バッテリ11とサイドシル17との間で潰れ変形する。これにより、側突により発生した衝撃を吸収することができる。 The end of the battery duct 14 on the vehicle inner side is in contact with the battery 11 . Therefore, in the event of a side collision, the battery duct 14 is crushed and deformed between the battery 11 and the side sill 17 by being pushed from the outside of the vehicle by the side sill 17 . As a result, it is possible to absorb the impact caused by the side collision.

本実施形態では、上記したようにバッテリダクト14と空調ダクト152とが重畳するように配置されている。よって、空調ダクト152とバッテリダクト14とが、同時に潰れ変形を起こすことで、効果的に衝撃を吸収し、バッテリ11に及ぶ衝撃を緩和することができる。 In this embodiment, as described above, the battery duct 14 and the air conditioning duct 152 are arranged so as to overlap each other. Therefore, the air-conditioning duct 152 and the battery duct 14 are crushed and deformed at the same time, thereby effectively absorbing the impact and mitigating the impact on the battery 11 .

図4の斜視図を参照して、他の形態に係るバッテリ保護構造10の構成を説明する。図4に示すバッテリ保護構造10の構成は、基本的には図1に示したものと同様であり、ここでは、空調ダクト152がクロスメンバ121およびクロスメンバ122の両方を貫通している。 A configuration of a battery protection structure 10 according to another embodiment will be described with reference to the perspective view of FIG. The configuration of battery protection structure 10 shown in FIG. 4 is basically the same as that shown in FIG.

具体的には、前方側に配置されたクロスメンバ121には第1貫通孔131が形成され、後方側に配置されたクロスメンバ122には第2貫通孔132が形成されている。また、空調ダクト152の前方部分は第1貫通孔131を貫通し、空調ダクト152の後方部分は第2貫通孔132を貫通している。 Specifically, a first through hole 131 is formed in the cross member 121 arranged on the front side, and a second through hole 132 is formed in the cross member 122 arranged on the rear side. Also, the front portion of the air conditioning duct 152 passes through the first through hole 131 , and the rear portion of the air conditioning duct 152 passes through the second through hole 132 .

係る構成により、空調ダクト152の前方部分は第1貫通孔131を貫通することで支持され、空調ダクト152の後方部分は第2貫通孔132を貫通することで支持されている。よって、側突が発生した際に、空調ダクト152はより強固に支持されることから、空調ダクト152によりバッテリ11を側突から保護する効果を大きくすることができる。 With such a configuration, the front portion of the air conditioning duct 152 is supported by passing through the first through hole 131 , and the rear portion of the air conditioning duct 152 is supported by passing through the second through hole 132 . Therefore, when a side collision occurs, the air conditioning duct 152 is supported more firmly, so that the effect of protecting the battery 11 from the side collision by the air conditioning duct 152 can be increased.

以上、本発明の実施形態について説明したが、本発明は、これに限定されるものではなく、本発明の要旨を逸脱しない範囲で変更が可能である。また、上記した各形態は相互に組み合わせることが可能である。 Although the embodiments of the present invention have been described above, the present invention is not limited to these, and modifications can be made without departing from the gist of the present invention. In addition, each form described above can be combined with each other.

例えば、図1に示したバッテリ保護構造10では、バッテリ11の車両外側である右側に空調ダクト152およびバッテリダクト14を配置することで、車両外側である右側からの側突からバッテリ11を保護したが、バッテリ11の後方側に空調ダクト152およびバッテリダクト14を配置することで、後方からの衝突からバッテリ11を保護することもできる。 For example, in the battery protection structure 10 shown in FIG. 1, the air conditioning duct 152 and the battery duct 14 are arranged on the right side of the battery 11, which is the outside of the vehicle, to protect the battery 11 from a side collision from the right side, which is the outside of the vehicle. However, by arranging the air conditioning duct 152 and the battery duct 14 on the rear side of the battery 11, the battery 11 can also be protected from a rear collision.
